Abstract

Zinc oxide particles are treated to absorb at least one compound selected from unsubstituted acyclic aliphatic mono- and polycarboxylic acids having no carbon chain longer than 10 atoms and their anhydrides, acyclic aliphatic mono- and polycarboxylic acids substituted by water-solubilizing groups, and salts of such unsubstituted and substituted acids. With most of these compounds it is thought that an interchange of cations will occur at the zinc oxide surface. A list of suitable compounds is given in the Specification. Various other organic compounds are suggested for use in combination with the above compounds to treat the zinc oxide. They are aliphatic mono- and poly-sulphonic acids and their salts; aliphatic boric acid compounds and their salts; aromatic mono- and poly-carboxylic acids and their salts and anhydrides; and aromatic sulphonic acid compounds and their salts. The aliphatic carboxylic acid(s) with or without the additional compounds suggested above will be termed a "treating agent." The zinc oxide particles may be contacted with the treating agent in the following ways: the zinc oxide may be exposed to a gaseous form of the treating agent; the treating agent may be added to an aqueous or organic dispersion of the oxide; or the zinc oxide may be dispersed in a binder solution and used to form a photoconductive layer on a backing which comprises a layer containing a sufficient concentration of treating agent to ensure that the treating agent diffuses into the zinc oxide layer during the coating operation or during storage prior to use-alternatively the treating agent may be allowed to diffuse from a layer applied over a resin-bound layer of zinc oxide.
